CC490K Brass vs. CR022A Copper

Both CC490K brass and CR022A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 84% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is CC490K brass and the bottom bar is CR022A copper.
